Buddha had nothing when he died. By modern standards he was destitute and homeless. Yet he died not being afraid of death (and isn’t it the life’s biggest achievement?). He died in peace. He made a huge difference in many lives and his name would outlive him by centuries. Minimalism, subtracting rather than adding (in any area of life, not just material wealth, eg thoughts, emotions, wants) is often a great way to purify oneself and focus on what’s important.
